I haven't really started vidding too much, as the computer I have right now uhm..Sucks

. Once I get my laptop, I plan on vidding quite a bit.
I remember reading on another forum that if you change your system properties so that the hardware acceleration is at "None" your recording device will lag much less.
It should look something like that, except you'll put the bar on None, instead of full.
I think I did try this at one point, and it did help. If someone who records a bit more frequently could test this out and reply, that would be great. (Just remember to put hardware acceleration back at full/whatever when you are done

)
